In addition to your control, the Honeywell L6006C 1010, Honeywell's L8124A,C and 8151A are triple aquastats similar in function, often used to control zone valves. Honeywell for a short time was selling the endwitch as a replacement part but last I saw that had been discontinued. Priority Operation: When zone 3 is switched to the priority setting and is actuated, all other zones will stop operation until zone 3 is satisfied. For the second circuit to the relay, I'm assuming the relay is attached to the circulator pump itself. A wiring diagram is a simplified conventional pictorial depiction of an electric circuit.
Also the zone valves are 4 wire with and end switch. The correct wiring depends on the zone valve models. On the t'stats, what is the purpose of the extra wire? The choice of slightly larger pipe size is preferable to a more powerful circulator. For each thermostat located in the home, there will be a zone valve wired to the boiler to control the flow of hot water or steam to the respective area heater. Do not use excessive flux or solder or some may work its way into valve.
Turn off the power supply to the boiler either by turning off an electrical switch or by shutting off the circuit breakers connected to the boiler. Gallery of Zone valve wiring diagram. A wiring diagram is a simplified standard photographic representation of an electrical circuit. There is an upstairs zone and a downstairs zone. A wiring diagram is usually made use of to repair issues and to make sure that the links have been made which everything exists. Meenan provides heating, heat pump, and air conditioning repair services in Maryland, Washington D.
The thermostat wires open the zone valve. The thermostat is basically operating as a low voltage switch. It depends on whether you have the 'new' or the 'old' style valves. Do not disassemble the valve base. Depending on exactly what the guy did, how he connected the one thermostat, it's possible that he has stressed the thermostat. I was able to get to the back where the plate is to get to the head. I will post back tomorrow with my results.
Currently I have progammable white rodgers t-stats. Instead of having one central thermostat for the whole system and heating the entire structure you can choose to heat only those spaces that are properly zoned thereby saving you money in energy use. I am ready to order a motor and 2 two Way Powerhead Conversion Kits. I believe the terminals I put the red wires on are the tt terminals. The use of strainers reduces the possibility of solder pieces or other debris holding a valve open.
On 2015-10-01 by Anonymous Hey Guys - transformers are rated for Va, Zone valves are also rated at specific Va, you cant say 1 transformer will power 5 zone valves, what if its a 25 Va transformer? Brief component descriptions are provided, along with updated contact and website details for most major manufacturers. How Are Multiple Zone Valves Wired? For some unknown reason he had all 4 zone valves connected to only one thermostat controlling the whole house. In addition to providing concise details of nearly 500 different boilers fuelled by electric, gas, oil and solid fuel, and over 400 programmers and time switches, this invaluable resource also features numerous easy-to-understand wiring diagrams with notes on all definitive systems. The Language of Circuitry Initially, allow s consider some of terms that you will certainly have to recognize: Voltage: Measured in volts V , voltage is the pressure or pressure of electrical power. Use these labels to help you make the appropriate wiring connections. A control box is wired to thermostats in your house and controls the zone valves.
Wire one terminal of the transformer to the thermostat and connect the first terminal of the zone valve operator to the other terminal of the thermostat. For switching multiple zone valves with one thermostat you may need to have the thermostat control a switching relay that in turn switches the gang of multiple zones. We include wiring diagrams and installation instructions for most zone valve model and multi-zone controllers, and we describe special wiring problems that can occur if you mix different types, brands, or models of heating zone valves on the same hydronic heating hot water heating system. Consequently, double check everything before you turn the power on. Circuitry layouts show how the cords are connected as well as where they should located in the real tool, in addition to the physical links in between all the components. I am thinking he purchased the wrong aqua stat. It is gauged in Amperes Amps , as well as can just flow when a voltage supply is connected.
While they could and will obtain extremely complicated, these are just a few of the common graphics to obtain your ground on. Watch out: also look for a leak into the hydronic system that could be pushing the pressure up abnormally, such as a leaky tankless coil if you have one. It is for both domestic hot water and heat in a radiant heat floor. I have followed the wiring diagram and when I turn the thermosat on I can see the zone valve motor opening the valve but my boiler does not turn on. If no voltage present, and proper input voltage is present, replace transformer. Systems with old mercury switch thermostats you could also blow the heating anticipator. The heating system should come on.
We include wiring diagrams and installation instructions for most zone valve model and multi-zone controllers, and we describe special wiring problems that can occur if you mix different types, brands, or models of heating zone valves on the same hydronic heating hot water heating system. And if you want to see more images more we recommend the gallery below, you can see the picture as a reference design from your Honeywell Zone Valve Wiring Diagram. In fact Zone-A-Trol zone valve installation instructions carried this warning: Zone-A-Trol Valves should not be wired in the same circuit with zone valves of a different make or manufacturer without first consulting your local Zone-A-Trol representative or our factory engineering department for special wiring information. This controller permits setting zone 3 to a priority setting that stops other zones for up to one hour such as to assure providing domestic hot water in an indirect-fired water heater. Heating system should be off demand circulation systems. Number 18 wire is sufficient and it does not need to be shielded.
